Origin:
Nursery
produced variegated cultivar.
T. roseiflorus
is belived to come from
Mexico (exact place of discovery unknown).
It is closely related to
T. lophophoroides, but its spines
are more numerous, Flower concolorous pink, opening less widely. However the exact identification
of this plant is dubious. The plants sold under this name are probably
of hybrid origin. Possibly between T. lophophoroides and
one of the dark spined species previously included in Gymnocactus
i.e. gielsdorfianus or viereckii.
Etymology: Roseiflorus derives from the Latin
words "rosea", meaning rose pink flowers.
Conservation status: Listed in
CITES Appendix I |
